I don't know for sure whether or not this is the one that does it, but I expect at some point this winter, the motherload of arctic air will attempt to make inroads deep into the south, maybe on several occasions. There is just too much cold air build up in canada and there is just so much potential with the indicies/teleconnections, that I believe we will have some true arctic air to deal with this year. I dont know that it will last long, but I expect it to show up sometime. Guess we'll see.

I think there's a lot of potential for this system. Timing is not super optimal right now. If the s/w ejects from the southwest a little earlier, we'll have plenty of cold air lingering from the weekend front. If it ejects a little later (or if the second front comes in a bit sooner) we could have a big phaser pulling cold air in on the back side.
